Claims priority, application Great Britain February 22, 1954 Claims. (Cl. 57-120) This invention relates to ring doubling or twisting machines and is concerned more particularly with the rings of such machines.

It is a usual practice to lubricate the rings by capillarity using wicks, each of which extends from an oil bath to a groove in the ring face where the traveller removes oil from the wick and distributes it around the ring face.

The object of my present invention is to provide improved ring lubricating means which enable higher spindle and therefore traveller speeds to be attained without the liability of brassing of the rings.

The invention consists in a ring doubling or twisting machine in which each ring is lubricated by a wick extending from an oil trough to a groove in the ring face, characterized in this that the up and down movement of the ring rail operates a recipricatory pump which supplies oil to said trough.

The invention further consists in a ring doubling or twisting machine as aforesaid having a pumping device connected to the ring rail which in one direction of movement of such rail delivers oil into the trough in or on the ring rail so that the said troughis flooded temporarily and the wicks give a copious supply to the rings, and in the other direction of movement returns surplus oil from the trough for repumping.

The invention further consists in a ring doubling or twisting machine as aforesaid in which a tube extends at its upper end into said trough where it is secured to the ring rail and at its lower end constitutes a piston in a fixed cylinder closed at its lower end, such cylinder receiving surplus oil draining from the rings through a filter in a reservoir which moves with the ring rail and has a drain tube connected to the reservoir and to the cylinder.

The invention further consists in a ring doubling or twisting machine as aforesaid, in which one end of each wick extends into the trough and the other end into the reservoir at a level lower than the upper end of the drain tube connected to the reservoir.

The invention further consists in a ring doubling or twisting machine as aforesaid, in which the trough is connected to a supplementary oil receptacle which is supplied from the trough and has a plunger therein by which its contents can be returned to the trough to flood the same temporarily.

The invention further consists in a ring doubling or twisting machine as aforesaid, in which the ring rail has a recess therein below each ring to receive surplus oil from the ring and deliver it to the reservoir.

Referring to the accompanying explanatory drawings:

In Figures 1-10, a indicates a length of ring rail with two rings b mounted therein in adapters c in a known manner; d are travellers on the rings. The rings have each an :oil groove e around its internal face with a wick f therein, the two ends of each wick being folded into a trough g formed in the ring rail a. A tube h which is secured in the ring rail in the manner shown to an enlarged scale in Figure 4 forms at its lower end a piston 1 moving in a closed bottom cylinder secured at its upper end in the cap k of a cylinder in connected integrally with a lower cylinder n which is secured by a clamp 0 (see Figure 9) to a fixed guide sleeve p secured in the fixed girder q. A guide rod r known as a poker, is secured at its upper end to the ring rail and moves through the sleeve p as the ring rail is raised and lowered in the usual manner. There are holes s through the cylinder within the cylinder m. A clamp 1 (see Figure 8) secures the tube It to a drain tube which moves in an outer tube secured in the cap k before referred to. The top of the tube u is secured to an annular oil reservoir v which has therein a filter w as shown in Figures 6 and 7. The top of the tube it comes below the level of the filtering material in the filter w so that only filtered oil flows down the tube it into the bottom of the fixed cylinder n. There is a supplementary oil receptacle at y in the ring rail (see Figure 1) with a plunger 2 therein which when depressed against the pressure of the spring 20 forces oil into the trough g to temporarily flood the wicks f in the trough.

Normally the cylinders m, n are filled with oil up to a level indicated at 21 in Figure 10 and this oil when the tube h with its piston i is in its raised position as shown in Figure 10 flows into the closed cylinder j which is filled thereby. As the ring rail a is lowered during the normal operation of the doubling or twisting machine, the hollow piston i first closes the holes .9 in the cylinder j and then displaces oil from said cylinder up the piston and over the top of the tube 11 so that such oil floods the trough g and the supplementary receptacle y.

It will be noted from Figures 3, 4 and 5 that the ring rail a is shaped at 23 to form a receptacle to receive oil dripping from the rings b, such oil flowing by tubes 24 to the oil reservoir v where it is filtered before passing down the tube u to the cylinder It.

When the oil trough g is full, the wicks feed a surplus of oil to the inside of the rings which floods the grooves e in the rings. The travellers d as they revolve around the rings throw off surplus oil which drips from the rings and as shown in Figures 4 and 5 dn'ps into the recesses 23 and drains into the reservoir v whence it returns by the tube a to the cylinder n for re-pumping.

plan view of the oil filter shown in is a sectional elevation 0n the line 14-14 If the doubling machine has been standing for some time so that the wicks have dried somewhat, the plunger z may be depressed to flood the wicks at starting up before the pump i moves downward to raise oil to the trough g and receptacle y.

When the ring rail is moved upwards, any surplus oil in the trough g above the level of the top of the tube h is drawn back into the pump cylinder.

The bottom of the cylinder n is closed by a plug which can be readily removed to clear the cylinder of any deposits. By releasing the clamps t and o the pumping unit can be lowered along the tube h so that the reservoir v and the filter w therein can be examined and cleaned.

In the arrangement shown in Figures 11-16, one end of each wick 1 which lubricates a ring I) extends into a trough 25 but the other end of the wick passes down a tube 26 into the reservoir v where it comes above the filter material w. The drain tube u comes into a space 27 into which filtered oil only can pass and its upper end extends above the level of the filtering material 'on to which the ends of the wicks f extend through the tubes 26 so that such wick ends are always immersed in oil and serve by capillarity to supply oil at all times to the internal surface of the rings. This renders the plunger z of Figure 1 unnecessary for starting up purposes.

By my improvement, ring doubling and twisting machines with the larger diameters of rings are enabled to run at higher speeds than at present usual without brassing of the rings.
